Deputy Adrienne Myers, who was arrested in October after allegedly brawling with two fellow deputies, is now accused of kicking a colleague in the groin as she was being booked in another case.

A Los Angeles County sheriff's deputy arrested last year on suspicion of assaulting fellow deputies has been accused of kicking another deputy in the groin this week, authorities said.

The latest incident occurred after sheriff's officials arrested Deputy Adrienne Myers, 36, on suspicion of making threats against a former friend, an official said. As Myers was being booked into the Century Regional Detention Facility in Lynwood, she allegedly lashed out. She was restrained soon after the groin kick, authorities said.

While she was handcuffed and being escorted to a booking cell, she allegedly kicked another deputy in the groin without provocation, officials said.

That deputy was not injured, sheriff's spokesman Steve Whitmore said, but Myers is now also being investigated for battery on a peace officer.

The deputy who was kicked worked at the same sheriff's station, in Norwalk, where Myers used to work, an official said.

Myers declined to comment through Whitmore. Gonzalez could not be reached for comment.

"Obviously, we take this very seriously," Whitmore said. "The investigation will move forward, and the appropriate action will be taken."

Myers was arrested in October after an early-morning brawl among three off-duty deputies at a La Mirada park. On-duty deputies were called after gunshots rang out. They found their three colleagues bloodied and apparently drunk, an official said.

Myers and the two other deputies were on their way home after being out at a bar when Myers and Deputy Judith Gonzalez began arguing. The argument allegedly turned physical and spilled out of the car.

Eventually, Myers stopped fighting Gonzalez and began fighting with the third deputy, an official said. Gonzalez allegedly went back to the car to get her gun. As Myers was on top of the third deputy, Gonzalez fired her weapon. No one was hit, according to the official, who requested anonymity because he is not authorized to discuss the case with the media.

Gonzalez was arrested on suspicion of felony assault with a deadly weapon and Myers on suspicion of felony battery.
